ments in that class of plows more especially designed as cotton plows and in which the plow point is so mounted that it can be adjusted to the desired angle with respect to the line of draft and according to the condi tion of the soil to be turnedand the particular work to be performed thereby.

Plows have heretofore been provided'that have means for tilting the plow point to the angles desired relativelyto the shoe or runner and such operation accomplished without stopping the plow, and in manytypes of plows such adjustments of the plow point is effected by swinging lever and rack devices. From practical experience with plows of the general type referred to, I have found their structure and operation open to objections, partly for the reason that the construction is costly and particularly for the reason that in setting the plow point to the different angles, the relative positions of the point, and the runner or shoe changes, and to such an extent that the point when set to dig a shallowfurrow frequently rises above the plane of the riding face of the runner or shoe, or when set to dig a deep furrow it projects so far below the said runner that a proper guiding or bearing of the plow is rendered diflicult.

My present invention, which specifically relates to improvements in the construction of plow shown in my Patent #992556 dated May 11, 1911, primarily has for its object to provide a plow of the character stated that can be cheaply made and in which "the set of the plow point is easily effected while running the plow andth-e setting of the said plow point either shallow or deep provided for without changing the relativepositions of the plow point and-therunner. a

In my patented plow, I havefound, from practical experience that the means for shifting the plow point, by reason of the direct connection between the slidable block that carries the plow point and the slotted beam, under some conditions, becomes.

: clogged subject to considerable friction,

adjusting or shifting point desired in the use of plows of this kind.

J present invention has. for its obj ecti to positively overcome the objections noted and to provide such connections between the plow point and the shifting or standard ledangerof their sticking, when clogged with dirt, is reduced to the minimum.

-Another object of my invention is to'pro. vide for an easy and positive relative shifts ing of the plow beam and the plow point during the setting or shifting of the plow whereby to set the draft end of the beam, high'or low,to suit the adjusted angle or pitchofthe plow; point.

tain details of construction and peculiar combination. Off parts, all of which will be. hereinafter fully explained, specifically pointed out in the appended claims and illuswhich: v v

Figure 1- is a perspective view ofmy imimproved plow, the point being adjusted to its most shallow position, andthe beam at its lowest position. Fig. 2 is a side elevation thereof, the parts being in' the position shown in Fig. 1, parts beingshown in section. Fig; 3 is a central vertical longitudia'rear perspective view of parts of the plow. Fig. 5 is. a perspective view of the plow tion hereinafter referred to.

In my present construction of plow, the beam 1 has its front end formed with a draft hook 1 and the rearendi thereof is curved downwardly and pivotally connects with the rear end ofthe runner 2 to which is conb eI QO. 1

combined standard and lever 3 includesthe slotted standard portion 31, the opposite members of. which straddle the front end of within the sweepof the standard 3 is formed nected theremovable shoe or-riding mem In my present, construction of plow, thewhich interferes with the quick and positive ver that frictional contact of the partsand 1 l My pr sent invention also embodies certrated in the accompanying drawing, in

nalsection, the plow point being at its maximum vertical or digging position." Fig. 4 is r point carrier or sliding head, parts of the slotted lever standard and the link connecp upper or handle memberBO, and the lower therunner and are pivotally connected thereto by thebolt 4. The plow beam at that part with a rack segment 32 .with which coacts adapted for. being reciprocably moved up and down within thesaid slotted standard,

as the latter is swungbackwardly and forwardly.

In my patent referred to the movement of the plow carrier is effected by joining the carrier with an eccentric slot in the beam. In practice, the slot in the standard frequently becomes clogged and the ground pressure on the plow is frequently such that the bolt sticks in the slot of the beam and renders the operation of the plow shifting means at times diflicult and unreliable.

In my present form of plow, I have dis pensed with the eccentric slot and cross bolt connection and in place thereof I connect the sliding plow carrying member to the beam by a compound lever connection, so arranged that a powerful leverage is applied to the point carrying member when the lever is swung, sufiioiently to positively overcome any tendency-of the plow point carrier sticking in the slotted standard. The compound lever connection referred to includes a bracket 80 fixedly secured to the curved end of the plow beam and projected inwardly therefrom and practically radially with respect to the pivotal connection of the standard.

A slotted link 9 is pivotally connected at one end 90 with the bracket 80 and at the I I other end 91, with the upper end of the point carrier, as is clearly shown in the drawing.

10 designates a second llnk connection that consists of two members 10 and disposed in a plane substantially at right angles'to the slotted link and projected vertically therefrom. Each of the link members 10 is pivotally connected, at the upper end, to a cross bolt 11 that passes through the upper end of the slotted standard and which carries a roller guide 12 thatvis held in engagement with the under edge of the plow beam.

'Thelower ends of the link members 80 are pivotally joined by .a crossbolt 13 to the link 1 member 9, while links 80 receive thelinks through the slot 15 and bolt 13 which carries a friction roller 14.

' 16 designates "the plow handles and 17 the side braces therefor.

" From the foregoing taken in connection with the drawing, the peculiar construction and the "advantages of my'present' construction of parts. will be readily apparent to those skilled in the art to which my type of plow belongs.

In my present construction when the coinbincd plow standard and lever is swung backwardly to give the plow its lowest inclination, for shallow digging, the slid-able plow carrier is at its lower position, since the slotted link is now at a substantially horizontal position and moved backwardly to its limit, see Fig. 2. It will also be observed that when swinging the lever backward the link arms 10 are forced downwardly and at the same time the roller bearing that engages the lower edge of the beam lowers and hence the forward end of the beam drops to its limit, it being understood that when the lever standard is swung in the opposite or forward direction, the plow point will be forced down into the ground and the frontend of the beam simultaneously raised (see full lines Fig. 8, dotted lines showing position when parts are as in Fig. 2) relatively to the degree in which the point is projected downwardly with respect to the runner.

It should be understood that the recess on the rear end of the runner 2 is of greater area than the lower end of the beam 1, so that the beam 1 may have a slight rocking movement on its pivotal connection with the runner 2, see Fig. 2 of the drawings. This is in order to enable the beam 1 and the runner 2 to have the necessary motion above described, the object of which is to enable the plow to be readily drawn through the ground and keep the plow point, when set to the position shown in Fig. 3, from tending to work up out of the ground, as would be the case were the beam 1, at its front end 1 lowered below the normal line of draft.

What I claim is:

1. In a plow having a fixed runner, a beam whose rear end curves downwardly and pivotally joins with the rear end of the runner, a plow carrying standard pivotally mounted on the front end of the runner, and means for reciprocatably moving the plow with respect to the standard, and simultaneously raising and lowering the plow beam as the said standard is swung in reverse directions.

9.. In a plow point having a fixed runner, a standard pivotally connected to the front end of the runner, a plow beam pivotally connected to the rear end of the runner, a plow point carried by the standard, and means for maintaining a relatively fixed relation between the plow point, the beam and the runner as the plow is adjusted to its digging positions.

3. In a plow of the character stated, the combination with the beam having a downwardly curved rear end, a runner pivotally mounted on the said end and projected forwardly therefrom, a standard pivotally mounted on the front end of the runner, a plow carried on the standard, and means operable through the backward and forward movements of the standard for efiecting a sliding movement of the plow on the standard and simultaneously raising and lowering the draft end of the plow beam.

4. In a plow, a plow carrying standard pivotally mounted to swing backwardly and forwardly, and means for reciprocably moving the plow point with respect to the standard, the said means comprising a plow carrier slidable on the standard, a bracket projected inwardly from the rear end of the beam, a slotted link slidable on the said bracket and pivotally connected to the plow carrier and a second link pivotally connected at one end to the slotted link, and pivotally connected at the upper end to the standard.

5. In a plow having a fixed runner, a beam having a downwardly curved rear end pivotally connected to the rear end of the runner, a standard pivotally connected to Copies of this patent may be obtained for the front end ofv the runner, a plow five cents each, by addressing the Commissioner of Washington, D. G. l

point carrier mounted to slide upon the standard, means for simultaneously moving the plow point on the standard and the beam relatively to theplow point when the said standard is moved backwardly or forwardly, the

- said means consisting of a slotted link piv otally connected to the upper end of the plow carrier and slidably connected with the beam, a second link disposed at substantially right angles to the slotted link and projected vertically therefrom, the said link being pivotally mounted on the slotted link and a pivotal connection that joins the said second link with the upper end of the standard, the said connection consisting of a cross bolt on the standard that bears against the under edge of the beam as the parts are adjusted or use.
